SMT - Square Mesh Track

SMT - Square Mesh Track was created by Cador1
Hello,
I'm a french researcher, Caen University in Normandy, working on SMT fences (and other re-use)  in rural Normandy's lanscapes and city buildings. I have a 4000 sites georeferenced with fences, portals, balconies, grids for wells, doghouses, henhouses, etc. in Bayeux and Caen area.

Almost all British Advanced Landing Grounds, and most of US ALG were totally or partilally (taxiways and hardstands) made of SMT. The rest was PSP for US airfields. We have no Sommerfeld (on runways but a lot for roads) or bars and rods tracks. So my subject concerns only SMT, aka BRC, or for the french countrymen "american mesh" (!).

I have few questions and need some help, please :

- are there a lot of fences in UK made with SMT today? where? In Normandy, near Caen and Bayeux, and Manche department, every village, farm, has many portion, easily visible when driving a car though the countryside.

- some people say that SMT was removed for British runways and move to Normandy due to a lack of material. Is it possible? can't imagine unplug the tracks, re-roll the SMT (I have a roll in my garden, trust me, it's impossible without a machine)

- how many kilometers we built by BRC company? I wrote them a mail, but no answer...

- do you know the airfields equiped with SMT in UK? I've seen pictures of ALG Christchurch. We can see plates of SMT (no rolls) near a Sommerfeld runway, maybe for comparison and tests.

Thanks for you interest in my research.

I can't answer your specific questions but I believe there have been some recorded sites in the UK where SMT has been used for farm fencing. There are also some locations that used the PSP track as well. I do know that PSP was used to make concrete sections for garages for cars as they were visible in some areas where the concrete was thin (1950s garage). I suspect SMT was also use for the same purpose. 

I did find some locations where SMT was used for fencing using Google Streetview around the site of UK advanced landing grounds.

Looking at your attached photo it reminded me that at some locations in London old wartime emergency stretchers are still being used as fences. They also used a square mesh but not the same as SMT which was much larger.

I do have one question, and that is, what is the life expectancy of SMT when used as fences? I suspect a lot of it must be rusting through by now.

There is a 1945 newspaper article that mentions BRC, this is the bit about SMT but send me your EMAIL address and I will send you the whole article.Staffordshire Advertiser - Saturday 29 December 1945Image © Successor rightsholder unknown.

B.R.C. SWITCH-OVER
The switch-over from war to peace-time production was rapidly carried into effect at the works of The British Reinforced Concrete Engineering Co.. Ltd, on the termination of hostilities. When the war in Europe ended the firm anticipated a slow up in the demand for square mesh track, which they had been supplying large quantities. and when approached by the War Office regarding a termination date for their contracts they were able ta close down on this work as soon as required. It was possible, therefore, for the firm to resume peace-time activities almost immediately after the end of the war with Japan. Since that time business has been confined to home and export work, devoted mainly to reconstruction.
The firm expects to be working to full capacity as soon as the present building restrictions are removed and when the construction of schools and the building of roads commence.
Of the firm*s war-time activities, it can be said that they carried out many important contracts for Government departments. Early in the war they designed a reinforced concicte air-raid shelter, and later made most of the mesh for bunks in Anderson shelters, bunks for tube stations and similar places safety, and then Morrison shelters.
 During the course of these contracts the firm had been experimenting with mesh to lay on the ground to form a temporary surface which was called square mesh track. Eventually this invention was perfected and very large quantities were supplied for advance air-fields, etc. The first cargo plane to land in France after D-Day landed on B.R.C. square mesh track, and. later, blown up, a temporary bridge of square mesh track was used.

BRC became part of BRC McMahon Reinforcements in 1970 which seems based in Tipperary.

BRC was a Staffordshiire company though originally from Manchester,

SMT is treated during it's fabrication with a rusted surface. So, the inner section is immunized. In Normandy, fence made of SMT are in brand new condition ! farmers still buy, exchange an sell it (that's the reason of my research as a geographer), and my neighbourgh took me a great lot of SMT rolls for his sheeps !

some samples of my surveys.
Balcony in the center town of Caen, bird cage, fence in town, fence of a garden at 50km from the closest airfield, a well shutter, all  made of SMT.

I noticed this bit in the newspaper report, did they make the stretchers that were supplied to the large air raid shelters?  A few years ago there were pictures of these being used end to end as fences in some housing estates.
